A photo can reveal more about a person than you might have thought. Just like looking in the eyes, photography can reveal your soul. What's more, a picture can bear different meanings. When looking at a photo of a newborn kid a woman will see her daughter's nose, eyes and chin, a man will pay attention to the absolutely different details.
Photography can provide not only a sense of place, but also have a historical and educational meaning. Thus, when young kids start asking parents about their family, a photo album can tell a lot.
